Stack Crush

Match tokenized stocks. Earn real shares on Base.

A match 3 game where every tile is a real Coinbase tokenized stock. Clear 40 levels across 4 chapters; level 10 opens an onchain stock vault and one tap claims real shares with zero gas. Every win is verified by replaying the moves on the server, and payouts are priced by Chainlink.

About

Who builds this, and the problems I keep researching.

Three years deep in crypto, building from Dhaka for teams everywhere. I ship DeFi protocols, token launchpads and agent tooling across EVM chains and Solana, and I keep going after the hard parts: FHE circuits, TEE enclaves and MEV resistant market structure.

Everything here is deployed, public and yours to audit. If something on this page looks like what your protocol needs, my inbox is open.

FHE prediction markets and TEE dark order books: confidential state that still settles on chain.

Confidential settlement
